This Mississippi Mud Cake is a chocolate lovers dream! A delicious homemade chocolate cake with melted marshmallows and warm chocolate frosting poured on top. Trust me, it’s as delicious as it sounds!
When it comes to sweets, chocolate cake is my weakness! Don’t get me wrong, I’m not one to discriminate against pies, cookies, or other baked treats. But even though I love them all, there’s no treat more tempting than chocolate cake! This particular version of chocolate cake goes above and beyond. It’s called a “Mississippi Mud” cake because of the layers of soft marshmallow and chocolate that make up the topping and frosting.
Not only is this Mississippi mud cake incredibly moist and flavorful, it’s also super EASY to make. The cake is baked in a 9×13” pan, and even though many people feel intimidated by cakes made from scratch, this chocolate cake recipe is one of the easiest homemade cakes you will ever make.
It’s adapted from my favorite Hershey’s Perfectly Chocolate Cake recipe. Instead of buttermilk I’ve used milk and sour cream. It bakes up sturdy enough to hold it’s own and serve easily from a 9×13” pan, but the crumb of the cake is still tender and soft. It’s SO GOOD!

In a large mixing bowl combine the flour, sugars, cocoa powder, baking powder, baking soda and salt.
Add oil, eggs, vanilla, milk and sour cream and mix until combined. Reduce speed and carefully pour in the boiling water. Beat on high speed for 1 minute to add air to the batter.
Pour batter into prepared pan. Bake for 28-33 minutes, or until a toothpick inserted in the center comes out clean.
Remove cake from oven and sprinkle marshmallows all over the top of the hot cake, completely covering it.
Return to oven (at 350 degrees F) for 2-3 minutes or until the marshmallows are just slightly puffed and melted.
Allow cake to cool completely before drizzling frosting on top.
Melt butter in a small saucepan over medium-high heat.
Add milk and cocoa powder and whisk well. Cook for about 2-3 more minutes, stirring constantly.
Remove from heat and stir in vanilla and powdered sugar. Use an electric mixer to make the frosting smooth.
Drizzle warm frosting immediately over cake. Refrigerate cake for about 30 minutes or until frosting has set. Store at room temperature.
